Abstract A new, convenient, ecofriendly synthesis of 3,5-diarylisoxazoles is reported from α,β-unsaturated ketoximes. Similarly, a novel synthesis of isoxazole carboxylic acids is also reported. Both the methods use efficient, environmentally friendly, and nontoxic iodoxybenzoic acid (IBX) as an oxidative cyclizing reagent. Easy procedure, environmentally benign reaction conditions, and nontoxicity
摘要 报道了一种以 α,β-不饱和酮肟为原料合成 3,5-二芳基异恶唑的新型、方便、环保的方法。类似地,还报道了异恶唑羧酸的新合成。这两种方法都使用高效、环保且无毒的碘氧基苯甲酸 (IBX) 作为氧化环化试剂。简单的程序、环境友好的反应条件和无毒是该方法的优点。图形概要
